Article Title: Inhibition of IL17A Using an Affibody Molecule Attenuates Inflammation in ApoE-Deficient Mice
doi: 10.3389/fcvm.2022.831039
Figure Lengend Snippet: In vitro efficacy of Affibody molecules in blocking IL17A induced responses in human aortic smooth muscle cells (SMCs) and mouse NIH/3T3 fibroblast cells. ELISA data showing the release of CXCL1 and IL6 into the medium (24 h) induced by increasing concentration of recombinant IL17A in human SMCs ( n = 4) (A,B) and CXCL1 in mouse 3T3 fibroblast cells ( n = 4) (E) . Human SMCs were stimulated with 5 ng/ml recombinant IL17A and without or with increasing concentrations of human Affibody molecules against IL17A and release of CXCL1 and IL6 (24 h) was assessed by ELISA ( n = 3) (C,D) . Mouse NIH/3T3 fibroblast cells were stimulated with 25 ng/ml recombinant IL17A and without or with increasing concentration of Affibody molecule against mouse IL17A and release of CXCL1 (24 h) was assessed by ELISA ( n = 5) (F) . Data is presented as mean ± SD. * p < 0.05, ** p < 0.01, *** p < 0.001 vs. control or as mentioned in graph (vs. IL17A).
Article Snippet: The next day, the media was replaced with fresh antibiotics free medium, and cells were treated with different concentrations of human or murine recombinant IL17A (R&D systems, USA) and cultured in the presence or absence of human or murine Affibody molecule at different concentrations to block IL17A (Affibody AB, Sweden), for 24 h. Unstimulated cells served as reference.
